In a business of entertainment and art, it is difficult to know who truly has your best interests at heart. You meet someone through networking who appears to have their stuff together because their portfolio looks good, could be a predator. You see someone in passing and you want to introduce yourself for a potential model, but they probably see you as someone trying to hit on them, especially if they have not been a model nor ever thought about it. There is no real equation that allows two people to come together and collaborate on beautiful art.
In the photography realm there are too many websites, too many professionals, and too many other photographers to contend with. Are you photos on this site or that site? Are you a member of this Facebook group or that Facebook group? So many things to consider when being online. I never wanted to be pigeon holed because I am a guy and I have a camera (pretty expensive equipment I might add).
